The Promise of Adulthood
How do we assure ourselves that [our severely disabled son] Ian is somehow contributing to all the choices that get made about what constitutes a good adult life for him? We have created new options for Ian and others as we have struggled to answer these ques-tions. We have also increased our understanding of what it means for someone who has a variety of severe disabilities to be adult.https://digitalcommons.chapman.edu/education_books/1014/thumbnail.jp
Winks, Blinks, Squints, and Twitches: Looking for Disability and Culture through Our Sonâs Left Eye
In this article, we argue that while an appreciation of disability\u27s cultural context is fundamental, we should be careful not to replace one essentialist version of disability with a new one. We look at the relational patterns that emerge from the specific circumstances of significant intellectual disability. This article follows Clifford Geertzâ wellâknown account of the multiple layers of cultural context and interpretive richness raised by even a seemingly simple act such as winking. By exploring the meaning of son\u27s ability to wink, we argue that intellectual disability may be interpreted as the absence of culture. The article goes on to explore the fragility of this relationship through the example of the cultural status of adulthood. Two recent reform initiatives â independent living and community inclusion â are discussed in light of this interpretation of intellectual disability. Implications for further research are briefly mentioned
âI don't eat when I'm sickâ: Older people's food and mealtime experiences in hospital
Background Inadequate dietary intake is a common problem amongst older acute-care patients and has been identified as an independent risk factor for in-hospital mortality. This study aimed to explore whether food and mealtime experiences contribute to inadequate dietary intake in older people during hospitalisation. Methods This was a qualitative phenomenological study, data for which were collected using semi-structured interviews over a three-week period. During this time, 26 patients aged 65 years or more, admitted to medical and surgical wards in a tertiary acute-care hospital, were asked to participate if they were observed to eat less than half of the meal offered at lunch. Participants provided their perspectives on food and mealtimes in hospital. Responses were recorded as hand-written notes, which were agreed with the interviewee, and analysed thematically using the framework method. Results Twenty-five older people were interviewed across six wards. Two main themes, âvalidating circumstancesâ and âhospital systemsâ, were identified. Each theme had several sub-themes. The sub-themes within validating circumstances included âexpectations in hospitalâ, âprioritising medical treatmentâ, âbeing inactiveâ, and âfeeling downâ. Those within âhospital systemsâ were âaccommodating inconvenienceâ, âinflexible systemsâ, and âmotivating encouragementâ. Conclusion Inadequate dietary intake by older hospital patients is complex and influenced by a range of barriers. Multilevel and multidisciplinary interventions based on a shared understanding of food and nutrition as an important component of hospital care are essential to improve dietary intake and reduce the risk of adverse clinical outcomes. Improving awareness of the importance of food for recovery amongst hospitalised older people and healthcare staff is a priority
Measurement of the CP violating phase Ïs using Bâ°/s â Ï(2S)Ï decays at the LHCb Experiment
The LHCb experiment at the Large Hadron Collider (LHC) at CERN is designed
to make precise measurements of processes including B and D mesons to test
the Standard Model (SM) predictions for CP violation, and to search for new
physics. From its inception one of the key aims of the LHCb collaboration has
been to precisely measure the CP violating phase Ïs, the weak phase due to the
interference between Bâ°/s -BÂŻâ°/s mixing and decay.
Having collected 3 fb-1 of data in Run 1, the combined results of LHCb
measurements of Ïs from various decay modes are in agreement with SM
predictions. The aim now is to improve the precision of the LHCb measurement
to be sensitive to any small deviation from the SM prediction of Ïs. One strategy
to achieve this, in addition to collecting more data, is to expand the number of
modes used to measure Ïs to improve the sensitivity of the combination. This
thesis presents the measurement of the CP violating phase Ïs in the yet unstudied
Bâ°/sâ Ï(2S)Ï decay mode.
In addition to providing a measurement of Ïs the study of this mode presents
an opportunity to confirm the lifetime difference of the Bâ°/s mass eigenstates âÎs,
currently only measured in the Bâ°/sâ JÏÏ decay mode. The results from 3 fb-1
of LHCb data are;
Ïs = 0:23+0:29-0:28 ± 0:02 rad,
âÎs = 0:066+0:041-0:044 ± 0:007 ps-1.
which are in agreement with the SM and the results from the LHCb measurement
from Bâ°/sâ JÏÏ decays
Family Portraits: Past and Present Representations of Parents in Special Education Text Books
This paper analyses the descriptions of families of children with disabilities as contained in introductory special education texts over the last 50 years. These text books are typically used in pre-service teacher education courses as surveys of the education of âexceptional childrenâ. The textbooks reflect the mainstream professional assumptions of the era about topics such as disability, special education, inclusion, and family/school linkages. However, they also shape the assumptions of the next generation of educators about these same topics. The paper summarises the results of a qualitative document analysis of a sample of these textbooks from two different eras. The paper compares and contrasts how the representations of families by leading scholars in special education have changed over time
3,4,5-Trichloroaniline Nephrotoxicity in Vitro: Potential Role of Free Radicals and Renal Biotransformation
Chloroanilines are widely used in the manufacture of drugs, pesticides and industrial intermediates. Among the trichloroanilines, 3,4,5-trichloroaniline (TCA) is the most potent nephrotoxicant in vivo. The purpose of this study was to examine the nephrotoxic potential of TCA in vitro and to determine if renal biotransformation and/or free radicals contributed to TCA cytotoxicity using isolated renal cortical cells (IRCC) from male Fischer 344 rats as the animal model. IRCC (~4 million cells/mL; 3 mL) were incubated with TCA (0, 0.1, 0.25, 0.5 or 1.0 mM) for 60â120 min. In some experiments, IRCC were pretreated with an antioxidant or a cytochrome P450 (CYP), flavin monooxygenase (FMO), cyclooxygenase or peroxidase inhibitor prior to incubation with dimethyl sulfoxide (control) or TCA (0.5 mM) for 120 min. At 60 min, TCA did not induce cytotoxicity, but induced cytotoxicity as early as 90 min with 0.5 mM or higher TCA and at 120 min with 0.1 mM or higher TCA, as evidenced by increased lactate dehydrogenase (LDH) release. Pretreatment with the CYP inhibitor piperonyl butoxide, the cyclooxygenase inhibitor indomethacin or the peroxidase inhibitor mercaptosuccinate attenuated TCA cytotoxicity, while pretreatment with FMO inhibitors or the CYP inhibitor metyrapone had no effect on TCA nephrotoxicity. Pretreatment with an antioxidant (α-tocopherol, glutathione, ascorbate or N-acetyl-L-cysteine) also reduced or completely blocked TCA cytotoxicity. These results indicate that TCA is directly nephrotoxic to IRCC in a time and concentration dependent manner. Bioactivation of TCA to toxic metabolites by CYP, cyclooxygenase and/or peroxidase contributes to the mechanism of TCA nephrotoxicity. Lastly, free radicals play a role in TCA cytotoxicity, although the exact nature of the origin of these radicals remains to be determined
A ROLE FOR RESEARCH IN INITIAL TEACHER EDUCATION ADMISSIONS: A CASE STUDY FROM ONE CANADIAN UNIVERSITY
This article argues for the importance of broad and on-going research to support initial or pre-service teacher education program admissions. Examples from a large initial teacher education program at one Canadian university illustrate the contributions of research to the evaluation and refinement of admission processes. These examples include anonymous surveys and confidential interviews of current pre-service teachers about their experiences of answering application questions about their social identity, how they decided to apply to and attend the program, and their expectations of teacher education and teaching. Research studies about the perspectives of and agreement among the application raters are also discussed. Finally, how the operational needs of the admission processes shape the research agenda and the emerging research findings in turn shape the admission processes is explored

Prophylactic antibiotic regimens in tumour surgery (PARITY): protocol for a multicentre randomised controlled study.
IntroductionLimb salvage with endoprosthetic reconstruction is the standard of care for the management of lower-extremity bone tumours in skeletally mature patients. The risk of deep postoperative infection in these procedures is high and the outcomes can be devastating. The most effective prophylactic antibiotic regimen remains unknown, and current clinical practice is highly varied. This trial will evaluate the effect of varying postoperative prophylactic antibiotic regimens on the incidence of deep infection following surgical excision and endoprosthetic reconstruction of lower-extremity bone tumours.Methods and analysisThis is a multicentre, blinded, randomised controlled trial, using a parallel two-arm design. 920 patients 15 years of age or older from 12 tertiary care centres across Canada and the USA who are undergoing surgical excision and endoprosthetic reconstruction of a primary bone tumour will receive either short (24 h) or long (5 days) duration postoperative antibiotics. Exclusion criteria include prior surgery or infection within the planned operative field, known colonisation with methicillin-resistant Staphylococcus aureus or vancomycin-resistant Enterococcus at enrolment, or allergy to the study antibiotics. The primary outcome will be rates of deep postoperative infections in each arm. Secondary outcomes will include type and frequency of antibiotic-related adverse events, patient functional outcomes and quality-of-life scores, reoperation and mortality. Randomisation will be blocked, with block sizes known only to the methods centre responsible for randomisation, and stratified by location of tumour and study centre. Patients, care givers and a Central Adjudication Committee will be blinded to treatment allocation. The analysis to compare groups will be performed using Cox regression and log-rank tests to compare survival functions at α=0.05.Ethics and disseminationThis study has ethics approval from the McMaster University/Hamilton Health Sciences Research Ethics Board (REB# 12-009). Successful completion will significantly impact on clinical practice and enhance patients' lives. More broadly, this trial will develop a network of collaboration from which further high-quality trials in Orthopaedic Oncology will follow
Examining predictors of school belonging using a socio-ecological perspective
Between the years of 2003â2015, the Programme for International Student Assessment (PISA) has identified a global trend signalling a decline in a sense of school belonging for secondary school students. Research has identified several factors that are positively related to school belonging, such as teacher support and academic motivation. However, little empirical research has been conducted to evaluate the relevant school belonging variables holistically and to assess their socio-ecological levels (e.g., student, microsystem, mesosystem) relative to the student. The purpose of this study is to assess the significant predictive variables within each socio-ecological level regarding school belonging. For this purpose, this study used data collected by PISA in 2015, focusing on data from 309,785 15-year-old students attending 12,668 schools in 52 countries around the world. Hierarchical multiple regression analysis was conducted to a) examine the empirical support for a layered structure of sense of school belonging, b) explore the contributions of variables in each layer of the socio-ecosystem to explain the variability in sense of school belonging and c) examine potential variations in this ability across schools and countries. The models provided support for the existence of such layers but also for some underlying relationships across the variables in the layers of the socio-ecosystem. The study then concludes with a discussion of the implications of the findings for school leaders, teachers and parents with respect to how school belonging approaches and strategies can be absorbed into existing practices and operations at school
